My invention relates to i shoe machinery such as staplers,'stitchers, lasters or the like and consists in a novel gauge, for spacing Q the sole or heel from the fastening parts of 5 the machines Y Y, i The main object of my invention is to provide a simple gauge'that may be horizontally and vertically adjusted without the-necessity of the operator moving from his working p0 sition, each adjustment being made by moving a control on the level with the gauge and within easy reach oftheoperator, standing in Working position at the end of the gauge, Another object of myinventiongis to provide a gaugethat may be readily swung away from the operator when it is not desirable to use said gauge;

Inthe accompanying drawings which illustrate a selected embodimentof my invention' Y 7 I Figure 1 is a side view of my invention applied to a stapler showing the throat block stapler horn with the toe of the shoe over the" anvil of said horn and under the throat block; Figur e' 2 is atop View of my gauge 'mechan1sm.-- I r i Figure dis a vertical section through my 7 gauge mechanismtaken substantiallyjonthe line'3'-3 of Figure 1., Figured is asideviewof the throat block, heel of the shoe and my gauge'verticallyiadjusted for applying staples to the heel of the shoe; v Y

Fixed tothe frame 1 of the stapler device is abracket 2.- Aplate orcradle 3 isislidably mounted ina recessin the lower face of said bracket. 1 Plate 3 has depending" flanges fl" to'which a gauge arm 5 is pivoted by pin 6;- Armf5 is retained in horizontal position by 7 means of a flat spring 7 secured atone end to one flange 4, a pin 8 passing throughthe flange with its head projecting outwardly from the flange with spring 7 bearing against'the head of pin 8. Y A hardened insert 9 marine engages the inner end of pin 8. Y I v I 1 Fulcrumedtobraoket 2 at'10isan armf11 with ahandle 12. V In'the 'bracket2alongthe 2 are which the inner end of the arm 11- would 0 describe upon the'movementof handle 12 is a pawl 17 fitting into" rat'chetlG;

curved slot Mounted on, arm 11 and adapted to project through slot B is a stud 14. Acrossplate' 3 and substantially-perpendiculartothe axis of arm 5 v is a straight grooveA; J ournaled on stud Y145and adapted .to fit into groove A is a roller 15; At the edge UNITED STATES, P E QFHCE of bracket 2 near handle 12, the bracketis V Iatchet ed" at 16; On handle 12. is

Thus as the handle 12 is moved to the left,

a spring I arm 11 swings onfulcrum 1Oiand "the"inner end of the arm moves tothe right, moving stud 1 1" inslot B so that roller 15 pushes against the side of groove A and thereby moves the; gauge mechanism attached thereto forward toward the throat block 13. Said .ratchet land pawl provide a mechanism for graduating said movement and yieldingly tion; I I Y i The front of gauge arm 5 has a member 18 which {is on approximately the same'level as of the stapler, and a'sh'oe mounted on the" bracket 2. Member '18 mounts a rotatable shank 19. with anzenlarged portion'20at the inner end thereof; -Member 18 has an inward- .ly "extending shoulder 21, Between portion 20 and shoulder 21 there is a coiledsprin g 22,

Member 18'has aline'd notches 23 on its outer face on opposite sidesiof shank 19. shank ,19 has a diametricalpin21j normally seated ofpin 27.v

The gauge'block is madefverticallyadjustablebec'a'useia different vertical position .of

the block'is' needed when work isto be done on f I '7 the heel from that whichis requiredfwhen work is to be-done on -the soleof the shoe;

Whenwork ing on the sole, the gauge'blockis, putiadjacentt'o sole itself as this member by prin Y is fairly regular in contour and in the finished 7 condition, except as to polishing, and the desired spacing of the staples with reference to the edge of the finished sole may be obtained by so placing the gauge block. But when working on the heel, the gauge block is low-' I ered to aposition-adjacentto'the surface of the body of the heel under the tap, as the tap is irregular in contour and is not'cut to the finished shapeiuntil after llZClS stapled on to; the heel. By placing the gaugeblockunder the tap and adjacent to the surface oflthe body ofthe heel, thedesiredspacing of the staples with reference to=the edge of the lin ished heel tap may be obtained,-
